BluePrint PSLS3760CTF Chevy LS 6.2L 530 HP EFI Retrofit Crate Engine

Description

Retrofit vintage muscle car engine compartments with the BluePrint PSLS3760CTF Pro Series Crate Engine. Displacing 6.2 liters, this fuel injected LS3 based platform generates 530 horsepower at 6200 RPM and 495 lb-ft torque at 4700 RPM. Complete with an intake manifold, drive by wire throttle body, standalone engine controller, and wire harness, it provides complete swap simplicity for project cars.

Solid cast iron block casting features heavy cylinder walls anchored by six bolt cross bolted main caps. The reciprocating kit contains a cast iron 3.622 inch stroke crankshaft, 6.098 inch connecting rods, and hypereutectic pistons inside 4.065 inch bores. The resulting 10.7:1 compression ratio operates on 93 octane pump gasoline. Total wet sump capacity holds six quarts, bringing dry weight to 475 lbs.

Key Features of BluePrint PSLS3760CTF

Buy BluePrint PSLS3760CTF crate engine packages to modernize project muscle cars with turn key electronic fuel injection and complete standalone engine control. The matched configuration mounts intake manifold, sensors, and throttle body straight to the engine for rapid installation.

• Electronic drive by wire throttle body manages intake airflow with smooth pedal calibration.
• Standalone engine wiring harness plugs straight into factory power feeds and dash instrumentation.
• LS3 rectangular port aluminum cylinder heads drop front axle weight while maximizing airflow.
• Pre calibrated engine control module self tunes fuel maps during normal street driving conditions.
• BluePrint PSLS3760CTF valvetrain components include beehive valve springs to prevent high speed valve bounce.
• Six bolt cross bolted iron main caps eliminate crank journal flex under elevated track RPM loads.
• Hydraulic roller camshaft profile creates sharp valve events without valve float at 6500 RPM.

Electronic Fuel Management Dyno Output

Dyno tests confirm this small block generates 530 brake horsepower at 6200 RPM and 495 lb-ft torque at 4700 RPM across an aggressive 2500 to 6500 RPM operating band. Cam duration measures 226 degrees intake and 236 degrees exhaust at 0.050 inch lift, producing 0.595 inch intake and 0.595 inch exhaust lift. The engine draws 13 in-Hg vacuum at 850 RPM on 93 octane fuel, maintaining 45 to 65 PSI hot oil pressure.

Chassis Clearance Drivetrain Integration Specs

Standard GM LS architecture drops between subframe rails on vintage Camaro, Chevelle, and C10 chassis when paired with swap engine mount plates. The crankshaft accepts 4L60E, 4L80E, or manual transmission bellhousings using standard LS flexplates or flywheels. Low profile intake components clear factory hood heights, while the retrofit oil pan clears intermediate steering linkages.

Engine Break In Service Protocols

Pre lube internal galleries with high zinc break in oil using an oil priming tank before starting the engine. This modern LS crate engine is not engineered for marine seawater cooling, forced induction boost exceeding six PSI on stock ring gaps, or unmetered nitrous systems.

• Drain initial break in oil and replace the spin on filter after the first 500 road miles.
• Perform regular oil changes every 3000 miles or six months with high zinc synthetic oil.
• Examine high pressure EFI fuel lines, electrical connections, and oxygen sensor fittings every 6000 street miles.

Turnkey Crate Manifest Warranty Protection

Factory coverage includes a 30-Month / 50,000-Mile limited warranty protecting internal components against manufacturing defect. The crate contains the assembled long block, EFI intake manifold, throttle body, ECU wiring harness, sensors, gas pedal, oil pan, valve covers, and certified dynamometer test sheet.
